And this is based on you using TW4? Or watching a video? Hey I was in LOVE with the TW video from last year's trade show...course 1/2 those things never made it into the Epic... Try an ASOP email, contacts, calendar - especially with an exchange account and see what's missing or broken by Samsung.
Aesthetically, I think they have a few good ideas- and their hardware is solid but they can't program their OS to save their lives. They need to toss in the towel and just rely on ASOP and focus on delivering great hardware.
